        "content": "Dealing with intermittent distortion on your Vocaster 2 when connected via a KVM to one of your Windows 11 machines can be frustrating. It sounds related to USB connectivity or driver/software settings rather than hardware damage. Below are possible causes and step-by-step ways to diagnose/fix the issue.\n\n---\n\n## \ud83d\udd27 What Could Be Causing It\n\nFrom what you describe, distortion that clears up after unplugging/replugging often points to one of these:\n\n- USB device glitching or being \u201csuspended\u201d (i.e. losing stable connection) ([learn.microsoft.com](https://learn.microsoft.com/en-us/troubleshoot/windows-client/setup-upgrade-and-drivers/usb-audio-video-devices-malfunction?utm_source=openai))  \n- Driver or firmware mismatch, or an older/buggy driver still in use ([downloads.focusrite.com](https://downloads.focusrite.com/index.php/focusrite/vocaster/vocaster-two?utm_source=openai))  \n- USB power management or selective suspend interfering with audio traffic, especially with latency-sensitive USB audio streaming ([knowledge.ni.com](https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P7POSA0&l=en-US&utm_source=openai))  \n- Conflicts from other USB devices (dongles, wireless peripherals) or USB port type (USB 2.0 vs 3.x) causing dropouts or distortion ([reddit.com](https://www.reddit.com/r/Focusrite/comments/1fhpm03?utm_source=openai))  \n- Audio format mismatches (e.g. sample rate, bit depth) or signal processing (enhancements) causing distortion when Windows tries to resample or apply effects ([support.microsoft.com](https://support.microsoft.com/en-us/windows/hardware/audio/fix-distorted-or-crackling-audio-in-windows?utm_source=openai))\n\n---\n\n## \u2705 Steps to Diagnose & Fix\n\nBelow are things to try \u2014 test after each to see if it solves the distortion. You may not need all.\n\n1. **Update Vocaster & Focusrite Drivers/Firmware**\n\n   - Download the latest driver from Focusrite for Vocaster Two (or your specific Vocaster model). ([downloads.focusrite.com](https://downloads.focusrite.com/index.php/focusrite/vocaster/vocaster-two?utm_source=openai))  \n   - Install any firmware updates if available (check Vocaster Hub or the manufacturer\u2019s website).\n\n2. **Use Rear USB Ports, Avoid Hubs or KVM Where Possible**\n\n   - If the Vocaster is connected through the KVM, try connecting it directly to a rear USB port on the motherboard. Users often find that direct connections are much more stable. ([reddit.com](https://www.reddit.com/r/musicproduction/comments/1e4nl96?utm_source=openai))  \n   - If KVM must be used, ensure it\u2019s of high quality, supports USB audio class devices reliably, and doesn\u2019t have severe cable length or interference issues.\n\n3. **Turn Off USB Power-Saving Features**\n\n   - Go into Control Panel \u2192 Power Options \u2192 *Advanced power settings* \u2192 expand **USB settings**, disable \u201cUSB selective suspend\u201d. ([knowledge.ni.com](https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P7POSA0&l=en-US&utm_source=openai))  \n   - In Device Manager, find USB Root Hubs / USB Controllers, right-click \u2192 Properties \u2192 Power Management tab \u2192 uncheck \u201cAllow the computer to turn off this device to save power\u201d.  \n   - Also disable \u201cfast startup\u201d (this sometimes skips proper initialization of USB devices) via Power Options. ([answers.microsoft.com](https://answers.microsoft.com/en-us/windows/forum/all/usb-device-recognition-is-spotty-and-causing/0f55ae16-f50b-4a56-81c3-32894bb63181?utm_source=openai))\n\n4. **Check Audio Format / Sample Rate / Bit Depth**\n\n   - Open Settings \u2192 System \u2192 Sound \u2192 Output \u2192 click your Vocaster \u2192 Advanced settings.  \n   - Try switching sample rate (e.g. 44.1 kHz \u2194 48 kHz) to see if distortion reduces.  \n   - Disable any \u201caudio enhancements\u201d (sometimes under \u201cRelated settings\u201d or in properties) \u2014 effects like \u201cloudness equalization\u201d, spatial sound, etc., especially when Windows is resampling the stream, can cause distortion. ([support.microsoft.com](https://support.microsoft.com/en-us/windows/hardware/audio/fix-distorted-or-crackling-audio-in-windows?utm_source=openai))\n\n5. **Reinstall / Reset Drivers**\n\n   - In Device Manager, uninstall the Vocaster (USB Audio) driver.  \n   - Unplug the device, reboot.  \n   - Plug it back in and let the fresh driver reinstall.  \n\n6. **Test Alternative Setup / Isolate Variables**\n\n   - On the much\u2010affected machine, disconnect all other USB devices except the Vocaster. See if distortion still occurs.  \n   - Swap cables or try a different USB cable (preferably shielded) to rule out cable/hardware issues.  \n   - If the other machine connected to the KVM doesn\u2019t have the problem, try mimicking its settings (USB port, driver version, power-settings) on the problematic PC.\n\n7. **Adjust USB/Chipset Drivers & BIOS Settings**\n\n   - Ensure motherboard chipset and USB controller drivers are up to date.  \n   - In BIOS/UEFI, check for USB settings like legacy USB support, or power settings related to USB. Sometimes there\u2019s a \u201cUSB sleep\u201d or \u201csuspend\u201d mode that can be disabled.  \n   - Also check whether the machine uses discrete TPM (dTPM) or firmware TPM \u2014 one known Windows 11 issue with discrete TPM causes USB audio/video devices to glitch (clicks/pops etc.). Microsoft released fixes for this in recent updates. ([learn.microsoft.com](https://learn.microsoft.com/en-us/troubleshoot/windows-client/setup-upgrade-and-drivers/usb-audio-video-devices-malfunction?utm_source=openai))\n\n---\n\n## \u26a1 Probable Solution for Your Case\n\nGiven the behavior (only one machine, resolved by physically unplugging/replugging), here\u2019s a likely scenario:\n\n- The problematic PC\u2019s USB-port is being suspended or losing sync due to power-management or signal issues, especially via the KVM path.  \n- Putting the Vocaster on a direct motherboard USB port and disabling all USB power-saving plus updating drivers/firmware will probably fix it.\n\n---\n\nIf you like, I can walk you through these steps tailored to your exact Vocaster model and motherboard so you can systematically test which fix actually solves it. Do you want to go ahead with that?"
